The effective role of by – product of PANI/V2O5 in improving the electrolytic performance of p – toluene sulphonic acid

Abstract

The use of liquid by-product obtained after the synthesis of electrode material as base fluid for the preparation of aqueous electrolytes instead of distilled water is beneficial in improving the electrolytic performance of aqueous electrolytes. The p – toluene sulphonic acid (PTSA) as electrolyte exhibited superior performance when prepared using the by-product obtained after the synthesis of PANI/V₂O₅ nanocomposite (PV) as a base fluid (PTSA+SL) to the electrolyte prepared using distilled water (PTSA). The PV exhibited 21.30 % higher energy storage in the presence (ITP) of PTSA+SL compared with that attained ITP of PTSA. The capacity (Q) and maximum energy stored (E_max) obtained ITP of PTSA are 1.13 C and 0.18 W h at 5 mV s¹. The Q and E_max achieved ITP of PTSA+SL are 1.38 C and 0.23 W h at 5 mV s¹. The utilization of by-products of the synthesis of electrode material back into the energy storage process brings this approach in to the umbrella of green energy storage processes. In addition, this approach personifies the concept of “waste to wealth” approach to work towards the sustainability in energy storage.
